摘要
目的:探讨胃癌螺旋CT各种征象与手术病理之间的关系。方法:对57例胃癌行低张水充盈螺旋CT三期增强扫描,并与手术病理对照。结果:螺旋CT对胃癌浸润深度、淋巴结转移和TNM分期评估的准确率分别为82.5%、78.9%和80.7%,均与手术病理一致(Kappa值分别为0.708,0.685和0.763)。结论:胃癌螺旋CT征象与手术病理之间具有相关性,可依据其影像表现特点推测出胃癌的病理学特性,从而指导手术及判断预后。
Objective：To study the relationship between spiral CT findings of gastric carcinomas and their manifestations in surgical pathology. Methods： A total of 57 patients with pathologically diagnosed as gastric cancer were examined with enhancing spiral CT using triple phase technique and the stomach was filled with water. Hypotonic agent was simultaneously used. Spiral CT findings were correlatively compared with surgical appearances and pathological staging. Results： The spiral CT accuracy rates of the infiltration depth of the stomach walls,lymph node metastasis and TNM staging in gastric cancer were 82.5 %,78.9 % and 80.7 % respectively. All of them were correlated with surgical appearances and pathological findings （Kappa values were 0. 708, 0. 685 and 0. 763, respectively）. Conclusion：There is correlationship among spiral CT findings and surgical appearances as well as pathological manifestations in gastric carcinoma. Thus, pre-operative spiral CT findings are capable of providing information on pathological features of gastric cancer,guidance for surgical planning as well as prognostic evaluation of the cases.
